流星模板助手的全局功能 [英] Global function for Meteor template helper

问题描述

我已经注册了这样的全局功能:

I have registered a global function like this:

Handlebars.registerHelper('dialogBoxOptions', function (callbackFunctionName){
    return {
        callBack: callbackFunctionName
    };
});

但是当我尝试按以下方式访问它时，我未定义dialogBoxOptions

but when I try to access it as below I get dialogBoxOptions is not defined

Template.myLlist.helpers({
    dOpt: dialogBoxOptions('dlgCB')
});

我已经尝试将其用作全局把手帮助程序和常规的javascript函数，但得到的结果相同.

I have tried this as a global handlebars helper and a regular javascript function but get the same result.

推荐答案

您无法通过这种方式访问​​车把助手，而可以在模板中访问它们:

You can't access handlebars helpers this way you can access them in the template:

<template name="myList">
     {{dialogBoxOptions.callback 'something'}}
</template>

如果要像现在一样在助手中访问它，则应该注册一个全局方法.您可以将其放在/lib/helpers.js

If you want to access it in your helper like you are doing now you should register a global method instead. You could put this in a file like /lib/helpers.js

dialogBoxOptions = function (callbackFunctionName){
    return {
        callBack: callbackFunctionName
    };
}

此外，如果您要创建全局模板帮助器，语法现在为:

Also if you want to make a global template helper, the syntax is now:

Template.registerHelper("dialogBoxOptions", function (param2) {
    return true;
});
